after playing with our RCP prototype application in the IDE for a
while, I was trying to finally deploy it to have it run on some testbed
without an IDE installed. So far, created a product definition from a
working launch configuration, went through some pain more or less
severe, resolved a bunch of dependency conflicts and missing
dependencies (which obviously seemed no problem in the launch
configuration), to finally end up with a message just alike that:

Cannot complete the install because of a conflicting dependency.
Software being installed: rcpshell 0.0.1 (rxp.shell.rcpshell 0.0.1)
Only one of the following can be installed at once:
Cannot satisfy dependency:

Hmmm... this is where, obviously, it seems to end. Which dependency is
conflicting? How to resolve this? How to, at the very least, figure out
what went wrong here? Given _this_ error, it seems next to impossible
to get anything done here... :(
